Create & name 700 folders, modify 700 files

Create and name 700 folders as per list + modify 700 files for landing pages I will supply a list of approx 700 names of towns, I need 700 folders created all named as per the list. Each folder must contain an HTML file which will be modified later. Copy and paste the folder 10 times and you get 1024 folder, select and delete 324. The copy and paste part should take 10 minutes. naming the folders I calculate at around 3 hours if you name 4 per minute. The next part is to go into each folder and open the html document using notepad, click on find / replace and type in a variable and the town name. It should be possible to easily do 3 of these per minute which totals 4 hours. I calculate the total time of this task at 7 hours plus several breaks as it is quite tiring.. please note it is approximately 700 and may be a bit less or maybe more, however I believe the figure to be nearer 600.
